Antioxidant Properties and Phenolic Composition of Propolis from Diverse Geographic Regions in Korea

Relationship between total phenolic contents and biological properties of propolis from 20 different regions in South Korea.

BACKGROUND Propolis (or bee glue), collected from botanical sources by honey bee, has been used as a popular natural remedies in folk medicine throughout the world. This study was conducted to assess growth inhibitory effects of ethanol extracts of propolis (EEPs) from 20 different regions in South Korea on human intestinal bacteria as well as their human β-amyloid precursor cleavage enzyme (BA...

Evaluation of phenolic compounds in Brazilian propolis from different geographic regions.

Chemometrics has been shown quite efficient to uncover relationships between chemical composition of a sample and its geographical origin. Forty propolis samples originated from the the South and South East of Brazil were analyzed by HPLC and 18 compounds of interest were studied which included: caffeic, p-coumaric and ferulic acids, and some of their derivatives, pinobanksin, a derivative of k...

Phenolic Composition of Propolis from China and from South America

Flavonoids and other phenolic compounds were determined in 15 samples of propolis originating from China, from Brazil, and from Uruguay. A total of 24 compounds were identified using mainly HPLC and a few other analytical methods. The most abundant com­ pounds found were benzoic acid and benzaldehyde derivatives, flavones, flavonols. and flavanones. 80% of the samples contained at least 22 g/10...
